So… you can’t prove that the unit will not shift wavelength into a harmful range. However, I can prove that by not subjecting myself any others to claimed-harmless light that I can prove it will not become be realized to be harmful.
Cool! You missed peak covid hysteria. But, there are people that will never recover/realize. Like the type of lunatic that would subject everyone to one of these for a thanksgiving dinner in 2025.
You also can't prove that your normal lightbulbs won't magically start outputting harmful wavelengths. Best to live in the dark I suppose.
Shrug. Nothing is 'harmless', including far-uv. Going outside in the sunshine isn't harmless. The stove in your kitchen isn't harmless. Can you prove your stove isn't going to explode some day and kill you? No, but you don't expect it to, in part because it complies with consensus product safety standards--germicidal UV products have their own standard, UL8802.
Far-uv is relatively new tech so it's reasonable to be wary, but I'm persuaded on the merits of evidence. Viruses definitely aren't harmless, and I'd rather not be catching random bugs on the regular if I can avoid it, or worry about my grandma catching flu in the hospital. Everyone has to make reasonable tradeoffs about risks and benefits.
